摘要：

This paper discusses the interference of common elements found in geological samples on the determination of Ca and Mg, by atomic absorption spectroscopy. It is shown that these interferences are practically eliminated by the fluoboric-boric matrix when determining Ca and Mg in standard silicate rocks, and Mg in some clays including Venezuelan laterites. © 1979.
